New PET-like plastic made directly from waste biomass
It is becoming increasingly obvious that moving away from fossil fuels and avoiding the accumulation of plastics in the environment are key to addressing the challenge of climate change. In that vein, there are considerable efforts to develop degrada.....»»
Officials sued over farm chemicals near Latino schools
For Nelly Vaquera-Boggs, the plastic tarps that cover strawberry fields in Monterey County, California, when they are being fumigated with toxic chemicals offer little comfort—especially when those fields are close to schools......»»
Chemists stabilize ethylene on silver in search for better ethylene purification technology
Production of ethylene is one of the most important chemical processes used today, with about 300 million metric tons of the tiny chemical produced each year. Ethylene gas is used to create everyday items like shopping bags and plastic film packaging.....»»
A machine learning-based approach to discover nanocomposite films for biodegradable plastic alternatives
The accumulation of plastic waste in natural environments is of utmost concern, as it is contributing to the destruction of ecosystems and is causing harm to aquatic life. In recent years, material scientists have thus been trying to identify all-nat.....»»
Researchers reveal complex response of microbial communities to wastewater fluctuations
Microbial communities in constructed wetland (CW) sediments are often disturbed by wastewater. It is necessary for the microbial community to maintain a relatively stable composition or biomass in order to continue to remove pollutants from wastewate.....»»
Can toothpaste tubes be recycled across the US? It"s getting closer
Toothpaste tubes and other squeezable plastic containers are getting closer to being more sustainable in the U.S. Some 90% of toothpaste tubes on the market are now made in a way that makes them compatible for recycling with HDPE, the same plastic us.....»»
Using CO₂ and biomass, researchers find path to more environmentally friendly recyclable plastics
Modern life relies on plastic. This lightweight, adaptable product is a cornerstone of packaging, medical equipment, the aerospace and automotive industries and more. But plastic waste remains a problem as it degrades in landfills and pollutes oceans.....»»
Self-embedding silver nanoparticles: Researchers find the "silver lining" in cotton gin waste
Cotton gin waste, also known as cotton gin trash, is a byproduct of the cotton ginning process and occurs when the cotton fibers are separated from the seed boll. For cotton gin waste, the treasure is its hidden potential to transform silver ions int.....»»
Malaysian graphite maker Graphjet plans Nevada factory
Graphjet Technology plans to build a facility in Nevada capable of turning agricultural waste into enough of the critical material for use in 100,000 electric vehicles per year......»»
A microbial plastic factory for high-quality green plastic
Engineered bacteria can produce a plastic modifier that makes renewably sourced plastic more processable, more fracture-resistant and highly biodegradable even in seawater. The Kobe University development provides a platform for the industrial-scale,.....»»
Protecting our planet: Five strategies for reducing plastic waste
Plastics are ubiquitous in our world, and given that plastic waste can take thousands of years to break down, there's more of it to be found on Earth every single day. Worse yet is the fact that the stuff doesn't easily decompose—it mostly just dis.....»»
How plants adjust their photosynthesis to changing light
Photosynthesis is the central process by which plants build up biomass using light, water, and carbon dioxide from the air. Gaining a detailed understanding of this process makes it possible to modify and thus optimize it—for example, with a view t.....»»
Cutting-edge enzyme research fights back against plastic pollution
Since the 1950s, the surge in global plastic production has paralleled a concerning rise in plastic waste. In the United States alone, a staggering 35 million tons of plastic waste were generated in 2017, with only a fraction being recycled or combus.....»»
Ocean floor a "reservoir" of plastic pollution, study finds
New research from CSIRO, Australia's national science agency, and the University of Toronto in Canada, estimates up to 11 million metric tons of plastic pollution is sitting on the ocean floor. The article, "Plastics in the deep sea—A global estima.....»»
NY "trash revolution" targets overflowing waste, and the rats feasting on it
New York City is iconic for its yellow taxis, pizza slices, bright lights on Broadway and its rats......»»
Study finds landfill point source emissions have an outsized impact and present opportunity to tackle US waste methane
A new study, led by Carbon Mapper scientists alongside researchers from NASA Jet Propulsion Laboratory, Arizona State University, University of Arizona, Scientific Aviation, and the U.S. Environmental Protection Agency, provides the largest comprehen.....»»
Attaching seaweed spores to used scallop shells could restore UK"s coastal kelp forests
Kelp spores are being seeded and grown on small rocks and scallop shells—a seafood waste product—in efforts to regenerate the UK's coastal kelp forests......»»
Plastic Omnium changes name as it adds software, lighting
The French supplier will be known as OPMobility, reflecting a broader ambition and new product line, executives said......»»
How eutrophication and climate change alter food webs in the Baltic Sea
Phytoplankton is the primary energy source for all marine ecosystems: These tiny plants floating in the seawater use photosynthesis to bind energy in the form of biomass, which is then passed on step by step in the marine food webs all the way to dif.....»»
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills, where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming......»»
Manila confronts its plastic problem through a community-guided protocol
Governments and international organizations have touted the circular economy, in which materials and products stay in circulation for as long as possible, as an antidote to our global plastic problem. (The equivalent of 2,000 garbage trucks of plasti.....»»
